Radiator bushing installation tips?

[vardenafil]

I’m trying to install new radiator mount bushings on my k20. I watched several videos and they just use a prybar to lift the support and slide the new bushings in. I can not get the support lifted high enough to slide the new bushings in. Is there something I have to loosen or in bolt first? I thought about getting a floor jack and trying to raise the support up but I’m afraid to mess something up. Any tips on how to make this job easier?

Are you talking about the rubber mounts where the core support mounts to the frame??

If so, you're going about it all wrong.. The best approach is to replace the cab mounts also. Here's how I did mine.

Loosen the six bolts (four on the cab and two on the core support) holding everything in place.. Remove one core support bolt and two cab support bolts on one side, doesn't matter which side.. Using a 4X4 board about 24" long and a floor jack under the rocker panel, lift the cab about 2".. Replace the 3 rubber mounts and install the new bolts and nuts only finger tight. Let the jack down and go to the other side.

Do the same thing with the 3 mounts on the other side.. Let the jack down and tighten all six bolts to the proper torque specs.

Should be able to lift enough to slide the bushing in. If you are trying to do it with the bolt in place, will be difficult. You would have to loosen all the cab bolts to get it high enough. Better to take radiator supports loose, lift radiator up so core support bolts can be removed.

I have the old rubber bushings out. I just can’t get the new ones in. I need another one 1/4 inch or so of lift. I’ll try loosening the cab mounts when it cools off.

Big ass 4x4 and a floor jack . If you not replacing the cab mounts you will have issues with alignment . I just did all 6 bushings on my 20 was fairly easy but my truck has no rust . I reused all the factory bolts

Got them on. Thanks for the help. I definitely need can mounts as well as they are rotten.

What 72 said for sure. If you've already done the support, then loosen those to do the cab, and torque all six as an assembly, in sequences, with the support's final torque being the last of it.
